[microblaze-uclinux] Suzaku Microblaze board freeze

[Eike Suthau <eike@xxxxxxxxxxxxxxxx>]

Hello and thank you very much for admitting me to the mailing list,

I'm in the process of developing the firmware for the
Microblaze-based Suzaku board by Atmark Techno.

I have encountered seemingly inevitable crashes of the board under high load.

I can provoke this behaviour by doing "cat /dev/urandom >/dev/null &" on the 
board and then continously pinging it from my PC (normal ping, no 
flood-ping). In my case it takes less than half an hour until the board 
freezes.
If I start the above command in foreground the effect goes away and I can 
"cat /dev/urandom >/dev/null" without any freezes.

Currently I have only a single board for testing so I'm not sure if it's a 
general bug or just my board (FPGA) doing this. I'd be very glad if someone 
would try to reproduce this on his own hardware.

Best regards,
eike
